C＃ - 如何计算.RTF / .TXT文件中的单词和字母？

Question

标题说明了一切..

搜索了Google和Stackoverflow，但没有找到类似的内容..

Answer 1

对于.txt文件，您可以使用regexp \b\w+\b。它将匹配所有出现的单词，例如：

var count = Regex.Matches(input, @"\b\w+\b").Count;

计算字母：

int count = input.Count(char.IsLetter);

Answer 2

static void Main()
{
     const string t1 = "To be or not to be, that is the question.";
     Console.WriteLine(WordCounting.CountWords1(t1));
     Console.WriteLine(WordCounting.CountWords2(t1));

     const string t2 = "Mary had a little lamb.";
     Console.WriteLine(WordCounting.CountWords1(t2));
     Console.WriteLine(WordCounting.CountWords2(t2));
}
